UNITED STATES SAMUEL NEUMANN, OF NEW YORK, N. Y.

WATER-MOTOR.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed June 28, 1920. Serial No. 392,263.

To all whom it may concern:

Be it known that I, SAMUEL NEUMANN, citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in VVater- Motors, of which the following is a specification.

The main object of this invention is the provision of a water motor of powerful, durable, and practical design.

Another object is the provision of such a motor which may be readily and easily operated and managed.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a front elevational view of my motor.

Fig. 2 is a side elevational view of the same, partly in section.

Fig. 3 is a side elevational view of the same in section, showing my preferred form of wheel.

Fig. 4 is a front elevational View of the same in central cross-section.

Fig. 5 is an enlarged cross-sectional view of my interlocking means between the shaft and the individual wheels.

Fig. 6 is a fragmentary cross-sectional view of another form of wheel.

Referring now in detail to the drawings, the numeral 1 represents the jacket surrounding my entire wheel, the latter indicated at 19, 20, and 21, comprising three separate units. Of course any number of such wheels may be used, as desired. Said jacket consists of an upper casing 10 and a lower casing 11, both said casings being secured by riveted plates 12.

Said wheels are loosely mounted upon a shaft 2 supported upon pedestals 3 and 4 in bearings 5. The usual fly wheel is indicated at 6. Two inlet pipes or nozzles are shown at 7 and 8, and a single outlet is shown at 9.

In the form shown in Fig. 2, each wheel comprises a frame surrounded by a circular band 13 having buckets 14 on the outer periphery thereof. In the form, which I prefer, shown in Fig. 3, the buckets are curved toward the left, so that the water entering through the nozzle 8 is deflected slightly downward into the recesses 15. I have provided on each of the separate wheels a pawl 17 and a spring 18 urging the former against a ratchet 16 rigid with the shaft 2, this mechanism being used when the wheel is to be driven constantly with a fixed load thereon.

For the case when the wheel is to be driven constantly against a load which is varied from time to time, I have provided a clutch or inter-locking mechanism shown in detail in Fig. 5. This mechanism is on each wheel in addition to the ratchet mechanism abovementioned, and when the former is used, the ratchet may be disconnected by lifting or removing the pawl 17 The shaft 2 is hollow and therethrough runs a rod 32 having a knob or handle 31 at its extending end. Each wheel is provided in its bearing surface with a recess 40. Pivotally attached at 35 to the rod 32 are dogs 34 engageable in the recesses and having cam-like extensions 37 adapted to be engaged by similar extensions 38 on the inner surface of the hollow shaft 2. Springs 36 normally urge the dogs into the recesses of the wheels. It is apparent that when the knob 31 is pressed inward, the dogs will engage the wheels and thus lock the latter upon the shaft 2, and when the knob is pulled outward the wheels will be released from the shaft and will'turn loosely thereon. WVhile the latter are thus loose on the shaft, the load may be changed and then the wheel may again be looked after the new load is ready to be applied.

In Fig. 6 I have illustrated another form of wheel, having the rim 13 provided with dovetail projections between which the individual blades or buckets 143 are separately attached. Thus, in case one blade is injured, it may be replaced without having to replace the entire wheel or rim.

Thus I have provided a water motor having many features to recommend it as a prime mover.

I claim:

1. A water motor comprising a casing, a hollow shaft journaled therein, a plurality of bucket wheels revoluble on said shaft, said wheels having recessed hubs, a rod slidable in said shaft, a plurality of spring impelled dogs pivoted in said rod, said dogs being normally engageable in the recesses of said wheels, and means formed internally in said shaft adapted to release said dogs upon moving said rod outwardly.

2. A water motor comprising a casing, a shaft ournaled therein, a plurality of wheels freely rotatable on said shaft, said Wheels and means for conneetingor disconnecting having undercut transverse recesses in their said Wheels relative to said shaft. peripheries, spaced teeth constituting buckets Signed at New York, in the county of New 10 fixed in the mentioned recesses, said elements York and State of New York this 12th day 5 being movable in close relation with the inof June, 1920.

terior of said casing, a separate Water inlet for each Wheel, a discharge common to all, SAMUEL NEUMANN.
